Quick af Wide prime

[charleyboy14]

Yo Peeps,

Quick question. need a wide prime. looking at either the sigma 20mm 1.8 or 24mm 1.8. i'll be shooting at f3.5 so not really fussed about stopping down. my question is, how accurate and quick do these lenses focus?

Cheers in advance

I have no complaints with the Sigma 20mm f1.8. It's a bit noisy in operation as it isn't HSM and not being HSM you don't get full time manual focus adjustment but apart from that it's perfectly fine IMVHO, and to answer your question I think it's fast and accurate.

It's not super sharp wide open but is certainly useable and it's very sharp stopped down just a bit to f2.2.
